Winstrol Inj 50 mg is a water-based Stanozolol injectable manufactured by Dragon Pharma and dosed at 50 mg/mL in a 10 mL vial.
Winstrol Inj 50 mg contains stanozolol, a synthetic anabolic-androgenic steroid derived from dihydrotestosterone. Stanozolol was first introduced to the market in 1962 and is classified as a Schedule III controlled substance in the United States. It is unique among anabolic steroids in that it is a heterocyclic steroid, containing a pyrazole ring fused to the A-ring of the steroid nucleus, which makes it resistant to hepatic metabolism and confers oral bioavailability.
In clinical practice, stanozolol has been indicated for the prophylactic treatment of hereditary angioedema, a rare genetic disorder characterized by recurrent episodes of severe swelling. It has also been used for aplastic anemia and other conditions, though it is rarely used for these indications today because better treatment options exist. The FDA-approved oral tablet formulation (WINSTROL, NDA 012885) was approved in 1984 and is now discontinued. In non-medical bodybuilding contexts, Winstrol Inj 50 mg is commonly referenced for its ability to promote muscle hardness, density, and vascularity, particularly during cutting phases when body fat is already low.
Stanozolol does not aromatize to estrogen, which means it does not cause water retention or gynecomastia. This anti-estrogenic property is frequently cited as a reason for its popularity during pre-contest preparation. However, stanozolol is a 17-alpha-alkylated compound, which carries significant hepatotoxic risk. It is prohibited at all times under the World Anti-Doping Agency (WADA) Prohibited List in the category of Anabolic Agents, and its metabolites can be detected in urine for extended periods.
Winstrol Inj 50 mg uses a water-based formulation, which differs from the oil-based carrier used in most injectable anabolic steroids. This water-based presentation allows for rapid absorption after injection and is the traditional formulation for injectable stanozolol. The 50 mg/mL concentration is a standard strength for this compound.
Stanozolol is a DHT-derived anabolic steroid with unique structural characteristics that distinguish it from other compounds. Its defining features include a pyrazole ring that confers oral bioavailability and resistance to hepatic breakdown, and the absence of aromatization.
Stanozolol is structurally derived from dihydrotestosterone but contains a pyrazole ring fused to the A-ring of the steroid nucleus. This structural modification makes stanozolol resistant to hepatic metabolism and confers oral bioavailability, which is unusual for a DHT-derived compound. The drug binds to the androgen receptor and promotes nitrogen retention, protein synthesis, and anabolic activity in skeletal muscle.
Unlike testosterone and many other anabolic steroids, stanozolol does not aromatize to estrogen. This means it does not produce estrogenic side effects such as water retention or gynecomastia. However, stanozolol is a 17-alpha-alkylated compound, a structural feature associated with hepatotoxicity. The drug is classified as a Schedule III controlled substance in the United States and is prohibited in sport by WADA at all times.
Historically, stanozolol was approved for hereditary angioedema, a condition characterized by recurrent episodes of severe swelling. It has also been used in veterinary medicine for conditions including poor appetite, anemia, and tracheal collapse in dogs, though it is no longer available as a manufactured veterinary medication in the United States and is only available through compounding pharmacies.
The water-based formulation of Winstrol Inj 50 mg provides rapid absorption after injection, with effects typically noted within hours to days. In non-medical contexts, the injectable form is commonly referenced as being administered every other day or daily due to its relatively short duration of action. The water-based carrier distinguishes it from oil-based injectables, which provide slower, more sustained release. Forum discussions commonly reference injectable stanozolol at 50 mg every other day as a typical protocol.
Dragon Pharma offers multiple stanozolol preparations for different preferences. The oral Winstrol 50 provides 50 mg stanozolol tablets, while Winstrol 10 offers a lower-dose oral option. For those seeking a non-aromatizing oral compound that is less hepatotoxic than stanozolol, Anavar 10 (oxandrolone) is commonly referenced in bodybuilding contexts.
In non-medical bodybuilding contexts, Winstrol is frequently stacked with a testosterone base such as Cypionate 250, which provides the anabolic foundation and maintains normal physiological function. Because stanozolol does not aromatize, it may reduce or eliminate the need for aromatase inhibitors when stacked with moderate doses of testosterone.
The information below is provided for educational reference only. Stanozolol is a prescription medication with limited current medical availability; medical use requires appropriate diagnosis, clinical supervision and ongoing monitoring. Non-medical use falls outside approved indications.
In non-medical bodybuilding contexts, Winstrol Inj 50 mg is commonly referenced in the range of 50 mg every other day, which equates to approximately 175–200 mg per week. Because of its relatively short duration of action and water-based formulation, the compound is typically administered every other day or daily. The 50 mg/mL concentration means that 1 mL provides 50 mg of stanozolol. Injectable stanozolol is commonly referenced at 50 mg every other day in forum discussions, with some users referencing daily administration for more stable blood levels.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Beginner (non-medical) | 25–50 mg | Every other day |
| Intermediate (non-medical) | 50 mg | Every other day or daily |
| Advanced (non-medical) | 50–100 mg | Daily |
In non-medical bodybuilding contexts, Winstrol is most commonly referenced as a cutting or pre-contest compound. It is frequently stacked with a testosterone base such as Cypionate 250, which provides the anabolic foundation and maintains normal physiological function. Cycle lengths of 4–8 weeks are commonly referenced for stanozolol due to its hepatotoxic potential as a 17-alpha-alkylated compound.
Because stanozolol does not aromatize, it may reduce or eliminate the need for aromatase inhibitors when stacked with moderate doses of testosterone. However, the combination of stanozolol with other 17-alpha-alkylated compounds should be avoided due to compounded hepatic stress.
As a DHT derivative, stanozolol can accelerate male pattern baldness in individuals who are genetically predisposed. Acne and increased skin oiliness are also commonly referenced. Unlike aromatizing compounds, it does not cause water retention or gynecomastia. Stanozolol can negatively affect lipid profiles, reducing HDL cholesterol and potentially increasing LDL, which may have a serious impact on cardiovascular risk.
Stanozolol is a 17-alpha-alkylated compound, which means it carries hepatotoxic risk. Published case reports have documented liver injury with stanozolol use. Liver function tests should be monitored during use. The injectable water-based formulation is not exempt from hepatotoxic risk, as the 17-alpha-alkyl group still confers hepatic exposure.
After completing a cycle with Winstrol Inj 50 mg, post-cycle therapy is commonly recommended in non-medical contexts to help restore endogenous testosterone production. Agents such as Clomid or Nolvadex are frequently referenced for this purpose. Because stanozolol has a relatively short duration of action, PCT can typically begin soon after the final injection. Bloodwork and, where possible, medical guidance can help inform recovery strategy.
Dosing strategies, support compounds and recovery protocols should be adjusted based on experience level and bloodwork where possible. The information above is for educational reference and does not constitute medical advice.
Stanozolol is a Schedule III controlled anabolic steroid that can affect hepatic, cardiovascular, endocrine and reproductive function. It is prohibited in sport by WADA at all times.
Stanozolol is classified as a Schedule III controlled substance in the United States and is subject to restrictions common to scheduled drugs. The FDA-approved oral formulation (WINSTROL, NDA 012885) was approved in 1984 for hereditary angioedema and is now discontinued. Non-medical use for bodybuilding or performance enhancement falls outside approved indications and may carry significant health risks.
Anabolic steroids in general have been associated with serious adverse effects including peliosis hepatis, liver cell tumors, and blood lipid changes that may increase the risk of atherosclerosis and coronary artery disease.
Use of stanozolol for bodybuilding or performance enhancement falls outside approved medical indications. Higher-than-physiologic exposure can increase the risk of serious hepatic, cardiovascular and endocrine complications.
Stanozolol is a 17-alpha-alkylated compound, and hepatotoxicity is a recognized risk. Published case reports have documented liver injury with stanozolol use. Liver function abnormalities, cholestatic jaundice and, in rare cases, hepatic tumors have been associated with C17-alpha-alkylated AAS use.
Cardiovascular effects include negative alterations in lipid profiles, with decreases in HDL cholesterol and increases in LDL. These changes may have a serious impact on the risk of atherosclerosis and coronary artery disease.
As a DHT derivative, stanozolol is associated with androgenic side effects including accelerated male pattern baldness, acne, and increased body hair growth. In women, virilization signs such as deepening of the voice, hirsutism, and clitoromegaly may occur and can be irreversible. Stanozolol suppresses endogenous testosterone production, which can lead to sexual dysfunction and testicular atrophy during use.
Anabolic steroids are contraindicated in certain circumstances. Contraindications include known or suspected carcinoma of the prostate or male breast, carcinoma of the breast in females with hypercalcemia, pregnancy, nephrosis or the nephritic phase of nephritis, and severe hepatic dysfunction. Caution is required in administering these agents to patients with cardiac, renal or hepatic disease, epilepsy, migraine or other conditions that may be aggravated by fluid retention.
If stanozolol is used in any context, monitoring of liver function, lipid profiles, and blood pressure is important given the compound's known effects. In non-medical bodybuilding contexts, bloodwork before, during, and after a cycle is commonly referenced as a risk-reduction strategy. Stanozolol metabolites can be detected in urine for extended periods, and athletes subject to drug testing should be aware that positive tests can result in sanctions of up to four years.

Answers to common questions about Winstrol Inj 50 mg, stanozolol, usage considerations, and product strength.
Winstrol Inj 50 mg contains stanozolol, which was historically approved for the prophylactic treatment of hereditary angioedema. In non-medical bodybuilding settings, Winstrol Inj 50 mg is commonly referenced for muscle hardness, density, and vascularity during cutting phases, though such use falls outside approved medical indications.
Because of its relatively short duration of action and water-based formulation, stanozolol is typically referenced as being administered every other day in non-medical contexts. The 50 mg/mL concentration means that 1 mL provides 50 mg of stanozolol. Some users reference daily administration for more stable blood levels.
In non-medical bodybuilding contexts, post-cycle therapy is commonly recommended after a stanozolol cycle to help restore endogenous testosterone production. Because of the relatively short duration of action, PCT can typically begin soon after the final injection. Agents such as Clomid or Nolvadex are commonly referenced for this purpose.
Stanozolol is a DHT-derived anabolic steroid that binds to the androgen receptor and promotes nitrogen retention, protein synthesis, and anabolic activity in muscle tissue. Unlike testosterone, stanozolol does not aromatize to estrogen, which means it does not cause water retention or gynecomastia.
Because of its water-based formulation, stanozolol is rapidly absorbed after injection. In non-medical contexts, users commonly reference noticing effects on muscle hardness and vascularity within the first week or two of use, particularly when body fat is already low.
There is no single compound that is universally best for cutting. Winstrol Inj 50 mg is commonly referenced in bodybuilding contexts for its ability to promote muscle hardness and vascularity without water retention. However, it carries hepatotoxic risk as a 17-alpha-alkylated compound. Other products such as Anavar 10 and Masteron 100 are also referenced for cutting purposes.
The primary difference is the administration route. Winstrol Inj 50 mg delivers stanozolol via intramuscular injection in a water-based carrier, while oral preparations such as Winstrol 50 are taken by mouth. Both ultimately provide the same active compound, though the injectable form bypasses initial first-pass hepatic metabolism. However, the 17-alpha-alkyl group still confers hepatotoxic risk regardless of route.
Winstrol Inj 50 mg contains stanozolol, a DHT-derived 17-alpha-alkylated anabolic steroid. Anavar 10 contains oxandrolone, another oral 17-alpha-alkylated anabolic steroid. Both are commonly referenced for cutting and lean-mass applications, but they have different potency profiles and side effect characteristics. Both carry hepatotoxic risk.
A milligram amount cannot be classified as appropriate or excessive without considering the specific context, individual response, and other factors. In non-medical bodybuilding contexts, stanozolol is commonly referenced at 50 mg every other day. Such use falls outside approved indications and stanozolol is known for significant side effect potential, including hepatotoxicity.
Winstrol Inj 50 mg is labeled at 50 mg of stanozolol per mL. It is supplied in a 10 mL vial, giving 500 mg of total labeled stanozolol content per vial.
Yes. Stanozolol is prohibited at all times under the World Anti-Doping Agency (WADA) Prohibited List in the category of Anabolic Agents. Urinary metabolites of stanozolol can be detected by methods such as gas chromatography-mass spectrometry and liquid chromatography tandem mass spectrometry at very high sensitivity. Long-term metabolites discovered in 2013 have dramatically extended the detection window, and athletes who test positive could potentially face a four-year sanction.
